Utilizing Smart Textiles-Enabled Sensorized Toy and Playful Interactions for Assessment of Psychomotor Development on Children

Figure 4

Graphical representation of data gathered by smart textile sensors included in the smart toy: (a) handgrip measure output data gathered from the press sensor and (b) stretch measure output data gathered from stretch sensor. In both cases the data is produced by the output of the arduino internal ADC available in the lilypad bounded between 0 and 1023. The red line represents the threshold that determines the existence of activity or not. The value of the threshold was defined by direct observation during the child-toy interaction.
